Abstract
Description
Technical Field
[0001] This utility model relates to the field of carburizing furnace lifting tools, specifically a carburizing furnace lifting tool. Background Technology
[0002] Carburizing is a common surface strengthening process in many industrial production processes and is widely used in machinery manufacturing, automotive industry and other fields. The carburizing furnace is the key equipment for carburizing, and the lifting equipment plays an indispensable role in the operation of the carburizing furnace.
[0003] Patent document CN219546503U discloses a carburizing furnace lifting device, including a lifting plate and a lifting device assembly connected to the lifting plate. In use, the lifting equipment is connected to the lifting plate. During lifting, the lifting plate is moved above the carburizing furnace, and then the lifting equipment moves the lifting plate downwards, which in turn moves several clamping plates downwards, allowing the clamping plates to fit over the outside of the carburizing furnace. Then, the telescopic end of the electric cylinder extends, moving the clamping plates towards the carburizing furnace, thus clamping and limiting the carburizing furnace. Limiting pins are then passed through the lifting ring at the top of the carburizing furnace, allowing the lifting equipment to lift the furnace. During the lifting and movement, the clamping plates clamp and limit the furnace body, preventing the carburizing furnace from shaking, thus facilitating the installation and subsequent disassembly and maintenance of the carburizing furnace.
[0004] The carburizing furnace lifting device disclosed in the above document has the following defects: When clamping workpieces, the technical solution often adopts a relatively fixed structure. For workpieces with different shapes, its clamping adaptability is poor, and it is difficult to make flexible adjustments according to the specific shape of the workpiece. When the workpiece has an irregular shape, the traditional lifting device may not be able to clamp it tightly, and it is easy to shake during the lifting process, which affects operational safety and production efficiency.
[0005] Therefore, it can be seen that the existing carburizing furnace lifting device does not have a good clamping mechanism, and it is necessary to improve the existing shortcomings and provide a new carburizing furnace lifting device. Utility Model Content
[0006] The purpose of this utility model is to provide a carburizing furnace lifting device to at least partially solve the problems of the prior art.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model relates to a carburizing furnace lifting device, comprising a lifting plate. Three sets of sliding grooves are formed on the upper surface of the lifting plate. Three sets of cylinders are fixedly installed on the upper surface of the lifting plate. A connecting plate is fixedly installed at the output end of each cylinder. Movable plates are slidably connected inside each sliding groove. The movable plates are connected to the connecting plates. A clamping plate is fixedly installed on one side of each movable plate. An auxiliary mechanism is installed inside each clamping plate. A lifting ring mechanism is fixedly installed on the upper surface of the lifting plate. The auxiliary mechanism includes sliding rods, limiting plates, threaded sleeves, and adjusting screws. The number of sliding rods is fixed to two sets. The two sets of sliding rods are slidably connected inside the clamping plates. A limiting plate is fixedly installed at one end of each set of sliding rods. A threaded sleeve is fixedly installed on one side of the limiting plate. An adjusting screw is threadedly connected inside the threaded sleeve. One end of the adjusting screw is rotatably connected to the inside of the movable plate.
[0009] Furthermore, the auxiliary mechanism also includes a throttle and a reinforcing plate. The throttle is fixedly installed at the end of the threaded sleeve away from the movable plate, and the reinforcing plate is fixedly installed at the end of the slide rod away from the limiting plate. The reinforcing plate is installed at an angle at one end of the slide rod.
[0010] Furthermore, the lifting ring mechanism includes a mounting cylinder, which is fixedly mounted on the upper surface of the lifting plate.
[0011] Furthermore, the lifting ring mechanism also includes a lifting ring body and a disassembly block. The lifting ring body is disposed above the mounting cylinder, and the disassembly block is fixedly installed on the lower surface of the lifting ring body.
[0012] Furthermore, the lifting ring mechanism also includes a mounting screw, and the mounting screw is fixedly installed on the lower surface of the disassembly block.
[0013] Furthermore, the mounting screw and the mounting cylinder are internally threaded.
[0014] This utility model has the following beneficial effects:
[0015] (1) This utility model rotates the handle, which drives the threaded sleeve to rotate. Since the threaded sleeve is threadedly connected to the adjusting screw and one end of the adjusting screw is rotatably connected to the inside of the movable plate, the threaded sleeve will move along the axial direction of the adjusting screw when it rotates. The movement of the threaded sleeve will drive the limit plate to move, and the limit plate will drive the slide rod to move. The reinforcing plate at one end of the slide rod can be adjusted according to the shape of the workpiece or the clamping requirements to further optimize the clamping effect, adapt to workpieces of different shapes, and improve the adaptability and stability of clamping.
[0016] (2) By means of threaded connection between the lifting ring body and the mounting cylinder in the lifting ring mechanism, when the lifting ring body is damaged, the mounting screw can be unscrewed from the inside of the mounting cylinder by turning the disassembly block with an external tool, so that the mounting cylinder can be replaced. This makes it convenient to operate when the lifting ring body is damaged or needs to be replaced, and improves the maintenance convenience of the entire lifting device.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4As shown, this utility model is a carburizing furnace lifting device, including a lifting plate 1. The upper surface of the lifting plate 1 is provided with three sets of sliding grooves 101. Three sets of cylinders 2 are fixedly installed on the upper surface of the lifting plate 1. The output end of each cylinder 2 is fixedly installed with a connecting plate 3. The sliding grooves 101 are all slidably connected with movable plates 4. The movable plates 4 are connected to the connecting plates 3. A clamping plate 5 is fixedly installed on one side of each movable plate 4. An auxiliary mechanism 6 is installed inside each clamping plate 5. A lifting ring mechanism 7 is fixedly installed on the upper surface of the lifting plate 1.
[0027] The lifting equipment is connected to the lifting plate 1 via the lifting ring body 702. Then, the lifting plate 1 is lowered to the workpiece. The cylinder 2 is started, and the output end of the cylinder 2 drives the connecting plate 3 to move. Since the movable plate 4 is connected to the connecting plate 3 and the movable plate 4 slides in the groove 101 opened on the upper surface of the lifting plate 1, the movable plate 4 will slide in the groove 101 with the movement of the connecting plate 3. The clamping plate 5 fixed on one side of the movable plate 4 will also move accordingly, thereby realizing the clamping action of the workpiece.
[0028] The auxiliary mechanism 6 includes a slide rod 601, a limiting plate 602, a threaded sleeve 603, and an adjusting screw 604. The number of slide rods 601 is fixed to two sets. The two sets of slide rods 601 are slidably connected inside the clamping plate 5. The limiting plate 602 is fixedly installed at one end of the two sets of slide rods 601. The threaded sleeve 603 is fixedly installed on one side of the limiting plate 602. The adjusting screw 604 is threadedly connected inside the threaded sleeve 603. One end of the adjusting screw 604 is rotatably connected to the inside of the movable plate 4.
[0029] The auxiliary mechanism 6 also includes a throttle 605 and a reinforcing plate 606. The throttle 605 is fixedly installed on the end of the threaded sleeve 603 away from the movable plate 4. The reinforcing plate 606 is fixedly installed on the end of the slide rod 601 away from the limiting plate 602. The reinforcing plate 606 is installed at an angle on one end of the slide rod 601.
[0030] When the clamping plate 5 has a gap in clamping the workpiece, the auxiliary mechanism 6 plays a supporting clamping role. Rotating the handle 605 causes the threaded sleeve 603 to rotate. Since the threaded sleeve 603 is threadedly connected to the adjusting screw 604 and one end of the adjusting screw 604 is rotatably connected to the inside of the movable plate 4, the threaded sleeve 603 will move along the axial direction of the adjusting screw 604 when it rotates. The movement of the threaded sleeve 603 will drive the limiting plate 602 to move, and the limiting plate 602 will drive the slide rod 601 to move. The reinforcing plate 606 at one end of the slide rod 601 can be adjusted in position according to the shape of the workpiece or clamping requirements to adapt to workpieces of different shapes, thereby improving the adaptability and stability of clamping.
[0031] The lifting ring mechanism 7 includes a mounting cylinder 701, which is fixedly mounted on the upper surface of the lifting plate 1;
[0032] The lifting ring mechanism 7 also includes a lifting ring body 702 and a disassembly block 703. The lifting ring body 702 is disposed above the mounting cylinder 701, and the disassembly block 703 is fixedly installed on the lower surface of the lifting ring body 702.
[0033] The lifting ring mechanism 7 also includes a mounting screw 704, which is fixedly mounted on the lower surface of the disassembly block 703;
[0034] The mounting screw 704 and the mounting sleeve 701 are internally threaded together;
[0035] The threaded connection between the lifting ring body 702 and the mounting cylinder 701 in the lifting ring mechanism 7 allows the mounting cylinder 701 to be replaced when the lifting ring body 702 is damaged, by using an external tool to unscrew the disassembly block 703 to remove the mounting screw 704 from the inside of the mounting cylinder 701. This facilitates operation when the lifting ring body 702 is damaged or needs to be replaced, improving the overall ease of maintenance of the lifting device.
[0036] In use, the lifting equipment is connected to the lifting plate 1 through the lifting ring body 702. Then, the lifting plate 1 is lowered to the workpiece, the cylinder 2 is started, and the output end of the cylinder 2 drives the connecting plate 3 to move. Since the movable plate 4 is connected to the connecting plate 3 and the movable plate 4 slides in the slide groove 101 opened on the upper surface of the lifting plate 1, the movable plate 4 will slide in the slide groove 101 with the movement of the connecting plate 3. The clamping plate 5 fixed on one side of the movable plate 4 will also move accordingly, thereby realizing the clamping action of the workpiece.
[0037] When the clamping plate 5 has a gap in clamping the workpiece, the auxiliary mechanism 6 plays a supporting clamping role. Rotating the handle 605 causes the threaded sleeve 603 to rotate. Since the threaded sleeve 603 is threadedly connected to the adjusting screw 604 and one end of the adjusting screw 604 is rotatably connected to the inside of the movable plate 4, the threaded sleeve 603 will move along the axial direction of the adjusting screw 604 when it rotates. The movement of the threaded sleeve 603 will drive the limiting plate 602 to move, and the limiting plate 602 will drive the slide rod 601 to move. The reinforcing plate 606 at one end of the slide rod 601 can be adjusted according to the shape of the workpiece or the clamping requirements to further optimize the clamping effect, adapt to workpieces of different shapes, and improve the adaptability and stability of clamping.
[0038] The threaded connection between the lifting ring body 702 and the mounting cylinder 701 in the lifting ring mechanism 7 allows the mounting cylinder 701 to be replaced when the lifting ring body 702 is damaged, by using an external tool to unscrew the disassembly block 703 to remove the mounting screw 704 from the inside of the mounting cylinder 701. This facilitates operation when the lifting ring body 702 is damaged or needs to be replaced, improving the overall ease of maintenance of the lifting device.
